[Anesthesia and acute hepatic porphyrias]
Summary
Patients with acute hepatic porphyrias (AHPs) must avoid certain anesthetic drugs that can trigger attacks. Regional anesthesia is preferred, while specific agents like fentanyl, nitrous oxide, and propofol are recommended for general anesthesia.
Area of Science:
- Biochemistry
- Genetics
- Pharmacology
Context:
- Acute hepatic porphyrias (AHPs) are inherited metabolic disorders affecting heme biosynthesis.
- Acute attacks in AHPs can be life-threatening and are often drug-induced.
- Common anesthetic agents pose a significant risk for precipitating AHP attacks.
Purpose:
- To provide guidance on anesthetic management for patients with acute hepatic porphyrias.
- To identify safe anesthetic agents and techniques for predisposed individuals.
- To outline treatment strategies for acute porphyria attacks.
Summary:
- Anesthetic management in acute hepatic porphyrias (AHPs) requires careful selection of agents to prevent dangerous attacks.
- Regional anesthesia is recommended as the safest option.
- For general anesthesia, a fentanyl-nitrous oxide regimen with propofol induction is advised.
- Treatment for acute attacks involves glucose and hematin administration.
Impact:
- Enhances patient safety by minimizing the risk of drug-induced porphyria attacks.
- Provides clinicians with evidence-based recommendations for anesthetic care in a high-risk patient population.
- Contributes to the understanding of drug-induced complications in inherited metabolic disorders.
